Title: Manufacture of tube containing optical fiber
Inventor: ARAKI NOBUO
IPC: G02B6/44
Filed: 1987-09-07
Abstract: PURPOSE:To manufacture a pipe containing a water-leak preventive optical fiber which is superior in performance at low cost, by filling a powdery high polymer water absorber loosely in the pipe by vibration as well as the optical fiber after inserting the optical fiber into the pipe previously. CONSTITUTION:The coil 5 of the pipe 1 is vibrated reciprocally along a spiral path from an optional point of the pip1, so the optical fiber 7 in the pipe 1 receives slantingly upward force from the in-pipe wall surface of the optical fiber 7 in the pipe 1 and bounces slantingly upward in the pipe 1 or slides on the internal wall surface of the pipe 1. Thus, the optical fiber 7 in the pipe 1 moves forth in the pipe while applied with conveying force in the circumferential direction of the coil 5 intermittently from the pipe internal wall to draw the optical fiber outside of the pipe 1 into the pipe 1. The powdery high polymer water absorber advances in the pipe in the same operation. Consequently, the pipe containing the water leak preventive optical fiber can be manufactured at low cost without affecting nor damaging the optical fiber.

Abstract: PURPOSE:To prevent abnormal overheated condition after stopping of operation by a method wherein a temperature detected by temperature sensing means set in a hot air heater is compared with a set temperature, a cooling method after stopping operation is determined and a convection flow fan is controlled by operation controlling means. CONSTITUTION:When a burner 2 is ignited and a convection flow fan 4 is operated, both hot air and combustion air are sucked from a suction port 5 through a filter 6. Then, hot air is sucked. Hot air is heat exchanged with a heat exchanger 3, mixed with combustion discharging gas and then blown from a blowing port 7 as hot air. After stopping operation, a temperature T1 detected by temperature sensing means 8 is compared with a predetermined temperature Tc by temperature discriminating means 10, and then a temperature T2 detected by temperature sensing means 9 is compared with a predetermined temperature Tf by temperature discriminating means 11. If a relation of T2>=Tf is accomplished, a fan 4 is rotated in its 'strong' step with operation control means 12 in response to a signal from the temperature discriminating means 11 and an inner side of the equipment is cooled. If a relation of T1>=Tc and a relation of T2>=Tf are satisfied, the fan 4 is rotated with 'weak' step and then 4 feeling of cool air is eliminated.
